Don Draper doesn't kill people. He doesn't cook or deal drugs. He doesn't oversee an organized-crime syndicate. Hell, he doesn't even use the F-word. But there's no question he's a bastard. He lies. He cheats. He undermines his colleagues in ways both overt and underhanded. And yet, in spite of it all, there has always been something about Don that makes us love him anyway. We know what a scoundrel he is, but we just can't quit him.
After a long span of increasingly airless personal drama, followed by last week's intrusion of a major historical tragedy, the show got back to its advertising roots with a vengeance. In fact, the show may have re-booted itself, as it did at the end of Season 3. For once again, the old Sterling Cooper etc. is no more.
